| 1. General Results, most used to calculate the result |
| A | name "jacsm.ro" is domain, public suffix is ".ro", top-level-domain is ".ro", top-level-domain-type is "country-code", Country is Romania, tld-manager is "National Institute for R&D in Informatics", num .ro-domains preloaded: 828 (complete: 263653)
|
| A | Good: All ip addresses are public addresses
|
| A | Good: No asked Authoritative Name Server had a timeout
|
| A | Good: No cookie sent via http.
|
| HSTS-Preload-Status: unknown. Domain never included in the Preload-list. Check https://hstspreload.org/ to learn some basics about the Google-Preload-List.

| A | http://www.jacsm.ro/ 80.96.123.239
| https://www.jacsm.ro/
| Correct redirect http - https with the same domain name

| B | https://www.jacsm.ro/.well-known/acme-challenge/check-your-website-dot-server-daten-dot-de
|
| Missing HSTS-Header
|
| C | Error - no version with Http-Status 200
|
| E | http://jacsm.ro/ 80.96.123.239
| https://www.jacsm.ro/
| Wrong redirect one domain http to other domain https. First redirect to https without new dns query, so the server can send the HSTS header. That's fundamental using HSTS (Http Strict Transport Security). First step: Add correct redirects http ⇒ https. Perhaps in your port 80 vHost something like "RewriteEngine on" + "RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]" (two rows, without the "). Don't add this in your port 443 vHost, that would create a loop. Then recheck your domain, should be Grade C. There is the rule to select one https version as preferred version.

| A | Good: All SOA have the same Serial Number
|
| Warning: No CAA entry with issue/issuewild found, every CAA can create a certificate. Read https://en.wikipedia.org/wiki/DNS_Certification_Authority_Authorization to learn some basics about the idea of CAA. Your name server must support such an entry. Not all dns providers support CAA entries.

| 4. Content- and Performance-critical Checks |
| A | Good: All checked attribute values are enclosed in quotation marks (" or ').
|
| A | Info: No img element found, no alt attribute checked
|
| A | Good: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
